Dissolution by water, especially water acidified by atmospheric carbon dioxide (producing carbonic acid) or soil acids.
Marble is composed primarily of the mineral calcium carbonate, modified to crystalline form by metamorphism of the parent limestone. Therefore karst features can develop in marble just as they can in unaltered limestone.
chemical weathering by acid rain.
Chemical change
A marble statue is likely to be affected more by chemical weathering compared to a granite statue. Marble is a softer and more porous rock than granite, making it more susceptible to chemical reactions with acids in the environment, such as acid rain. This can lead to the erosion and disintegration of the marble statue over time.
Okay, I will explain to you that, in the rainfall should had some kind of chemical like alkali, acid, salt, aldehyde, etc. Specially acid will interact with marble which contains calcium carbonate (CaCO3) to make the salt and liberates water vapour. The reason that surface of marble is not uniform as metal, so when the acid penetrates to the marble will make the result with porous coefficient differently. And you can see this very obviously this marbles surface will be rough touch. Of course this is long process not immediately after you fix the marble at the exposed area.
I suppose that a marble statue is more sensible (excepting wood statues).
Corrosion of marble is a chemical change. It occurs when the minerals in the marble undergo a chemical reaction with substances like acids or salts, leading to the deterioration of the marble's structure.
chemical weathering by acid rain.
Quartz is a mineral that is highly resistant to chemical weathering. Marble is a mineral that is more susceptible to chemical weathering.
Chemical change
Marble weathers faster than feldspar because marble is more susceptible to chemical weathering due to its composition of calcium carbonate, which reacts easily with acidic rainwater. In comparison, feldspar is more resistant to weathering due to its hardness and chemical stability.
Limestone and marble.

it speeds up the weathering process.
Becuase its wearing down the calcite and marble as it runs across it
Chemical weathering can dissolve the calcite in marble and limestone over time, especially in the presence of acidic rain or groundwater. This can cause the rocks to deteriorate, forming cracks and pits on their surface. The dissolution of calcite can also weaken the structure of the rocks, leading to physical weathering processes like erosion.

The answer is marble because it is like glass and if there were a piece on the ground it could be easily broken but if there were a tornado the tornado couldnt break it. Marble is very fragile.
